Just one more comment on the Robart struts. I felt that as they are shipped from Robart the internal spring is way too rigid. It doesn't give the shock absorption a strut like this is supposed to. I went to an auto parts store and purchased a same-size-but-softer-spring which did help some. I even ended up cutting that replacement spring and stretching it some to soften it some more. It works pretty well now and does take some of the landing shock out of the wing.
